if a new html5 serialisation mode  was specified that treated 
no-namespace and xhtml in similar ways then most of the differences 
between the existing html and xhtml output methods would be gone, the 
only difference being described here is whether you describe html5 
serialisation as a variant of the existing xhtml or html serialisation 
methods, I don't think it actually affects the behaviour.

xslt1 serialisation allowed prefixes to be changed (or dropped) but 
XSLT2 serialisation requires that prefixes be kept (so that documents 
using  qnames-in-content) may be reliably produced.

Of course, the generating templates may be written not to generate 
prefixes, but I don't think that's what you meant.

Not exactly, currently the html serialisation

http://www.w3.org/TR/xslt-xquery-serialization-30/#HTML_MARKUP

says

The HTML output method MUST NOT perform escaping for any text node 
descendant, nor for any attribute of an element node descendant, of a 
script or style element.


I think Henri is correct to say that that list could be extended to 
include more than just script and style.
